Lost your Android phone? Didn’t install a phone-finder? Have a Plan B.

Here’s hoping you never experience the sinking feeling you get when you realize your smartphone is missing.

And that sense of dread gets even worse when someone asks if you installed a phone-finding app on your device . . . and you have to confess that you did not.

However, if you’ve got an Android-based phone, there’s still hope, thanks to an app called Plan B from Lookout, a mobile software security developer. Plan B takes advantage of Android’s ability to remotely install an application onto the phone by way of the Android Market’s website.
